In this article, an innovative supervision system will be proposed that can observe and analyze health of Circuit Breaker’s trip coil. The proposed design also logs changes in the coil's quality and informs network supervisor in case of Circuit Breaker (CB) failure. This system injects small direct currents to the Circuit Breaker connections and the trip coil to compute CB’s health and characte...

generally, the failure rate and the repair time of system components are constant parameters in reliability assessment of electric distribution systems. a failure of component is resulted from failing in the operation or overloading. in addition, there exist cases where, the repair times of components are small and tolerable from customer point of view. thus, tolerable repair times may be overl...

Abstract: The application of electric field theory to widely different aspects of electrical insulation has led to more understanding the phenomena. Electric fields may be considered as the main reason for insulation failure. The purpose of this paper is to modify importance of analyzing electric field in insulation design. The SF6 circuit breaker is chosen as case study that encounters cri...

The automated circuit breaker diagnostic system described in this paper is an extension of the widely used portable circuit breaker testing device concept. The testing devices can be connected to the circuit breaker’s control circuit to record analog and digital signals. The automated system consists of a signal processing module and an expert system module. The two modules process the voltage ...

In a weak positional game, two players, Maker and Breaker, alternately claim vertices of a hypergraph until either Maker wins by getting a complete edge or all vertices are taken without this happening, a Breaker win. For the class of almost-disjoint hypergraphs of rank three (edges with up to three vertices only and edge-intersections on at most one vertex) we show how to find optimal strategi...

In addition to its role as an information carrier in gene expression, RNA is now recognized to carry out a broad range of biological functions, and novel activities continue to emerge on a regular basis. RNA molecules can act as catalysts in reversible phosphodiester-cleavage reactions (Fedor, 2000; Hutchins et al., 1986; Shih and Been, 2002), mediate splicing of premessenger RNA (Collins and G...

Longshore transport experiments were conducted in a large-scale physical model to evaluate predictions of the CERC formula with measured longshore sediment transport rates. It was found that the CERC formula produced reasonable estimates if the coefficient K was calibrated and applied to waves with similar breaker type. The calibrated K values are much smaller than values that are commonly used...
